Benefits of technology

"This patent describes a mobile communication device with a keypad assembly that provides tactile feedback to the user through a heating element. The device can sense input on the touch sensitive cover and activate the heating element based on the input to provide information to the user. The keypad assembly includes an enclosure that contains the heating element and a paraffin layer or gel that can expand to provide feedback to the user. The device can also display characters based on the position of the input on the touch sensitive surface. The technical effect of this invention is to provide a more intuitive and tactile user experience for mobile communication devices."

Problems solved by technology

Currently, there are no adequate solutions of providing tactile feedback to keypads formed of a single physical device or surface, such as a touch sensitive surface.

Abstract

A mobile communication device may include logic configured to receive input on a touch sensitive surface of a device and heat a substance to produce an expansion of the substance in response to the received input, where the expansion of the substance provides tactile feedback to a user indicating that the device has received the input.

Description

BACKGROUND OF THE INVENTION[0001]Implementations described herein relate generally to input devices, and more particularly, to handheld input devices that may provide tactile feedback.[0002]Devices, such as handheld mobile communication devices, conventionally include input devices that provide some form of tactile feedback to a user indicating that an input has been detected by the communication device. These conventional keypads are formed of physically distinct keys. Currently, there are no adequate solutions of providing tactile feedback to keypads formed of a single physical device or surface, such as a touch sensitive surface.SUMMARY OF THE INVENTION[0003]According to one aspect, a mobile communication device is provided. The mobile communication device may comprise a keypad assembly comprising a touch sensitive cover, a paraffin layer, a heating element and a display for displaying information, and logic configured to sense an input on the touch sensitive cover and activate t...
